Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to compare the maxillary
dental arch form and palatal vault form between 98 cerebral
palsied and 76 normal children. All subjects were divided
into three categories based on their dental eruption. The
cerebral palsy subjects were further divided into the
regional classifications of diplegia, paraplegia, hemiplegia,
and quadriplegia, and the descriptive classifications of
spasticity, athetosis, and mixed.
The maxillary dental arch form was described by an
index number which reflected intercuspid width, intermolar
width, anterior-posterior length, and degree of divergence
of the posterior segments. The palatal vault form v1as
described by the angle of divergence of the palatal walls
at an established reference point from a cross-sectional
view. All measurements were made from study models and
Xerox photocopies of study model cross-sections. In addition,
those occlusal discrepancies that were thought to influence
arch form, i.e., posterior unilateral and bilateral crossbite,
anterior crossbite, anterior open bite, and posterior
dental asymmetry were tabulated.
Statistical analysis of the results revealed no significant
difference in maxillary dental arch form between
the cerebral palsied and normal children. The same held
true for palatal vault form. Significant differences did
occur between primary, mixed, and permanent dentitions for
both cerebral palsied and non-handicapped groups. The results
suggest that the neuromuscular handicap has little effect
on the form of the maxillary dental arch. On the basis of
this study, it appears that there is no particular type of
maxillary arch form that is peculiar to cerebral palsy.
